Abstract
The invention relates to the drives for acoustic sources. A drive contains a rotary electric motor and an associated axle comprising at least one axle part, the outer cross-sectional contour of which is non-circular, but preferably smoothly rounded and has the form for example of an oval, and several pushers mounted radially relative to the axle with possibility of action on their internal ends in the radial direction by the noncircular part of axle at its rotation, during which the external ends of pushers are able to excite vibrational movement of the sound-emitting surfaces.
